1 also provide a device for throwing the rod or bar cl backwardly each time that it is fed forwardly by the lever d and this device consists of a spring 713, (reference being made to Fig. 5,) which is secured to the plate 36 of the frame and which operates in connection with a pin 72, secured to said rod or bar d, and each time that the rod or bar at is fed forwardly by the lever d the spring 7L2 will throw it back into position, so that the pawls 61 which are pivotally connected with the ends of the rod d, will engage with successive teeth on the saw.

The gear-wheel or pinion 81 on the lower end of the shaft 80 is provided with a cam m, which operates in connection with a cam-head m on the support of said shaft, and the shaft 80 is vertically movable by reason of this cam and cam-head, and the operation of the ma chine will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the fola lowing statement thereof.

The machineis operated by turning the crank 34,and this operation revolves the wheel 30, as will be readily understood, and the shaft 80 is continually revolved by means of the pinion or gear-wheel S1 and is also given an up-and-down motion by means of the cam m i and the cam-head m the downward motion being occasioned by gravity or any suitable means. In this operation the plate or attachment 91 and the arm or extension thereof revolve with the shaft 80, and the file-carriers 87 and 88 slide in the heads a the sides of the carriers being provided with flanges O, as shown in Fig. 15, which move in correspond ing grooves in the head (i and in the backward movement of said carriers they are raised by the cam m, so as to be disengaged from the teeth of the saw, and at the end of the backward movement they are brought into contact with said teeth, and the rear ends of the carriers maybe set laterally, as shown in dotted lines in Fig. 5, by means of setscrews P, which are shown in Fig. 1 and which press upon the bearing 89, with which the heads a are connected, the object of this arrangement being to provide means for adj usting the carriers to the position of the teeth of the saw.

The operation of setting the teeth is accomplished by means of the construction hereinbefore described and as shown in Figs. 1, 11, 12, and 13, and these devices are operated by the gear-wheel 52 on the shaft 51, said gearwheel being operated by the segmental gear 32 on the wheel 30. In the revolution of the shaft 51 the head of the quadrant '53 and the arm 54 thereof are turned with said shaft, and this operates the lever 59, and said lever 50 operates the setting-levers 72 and 73 on the shaft 63 and the setting-levers 74 and 75 on the shaft 62, this operation of said setting-levers being effected by the earns 67, 68, 09, and on the shaft 60, with which the lever 59 is connected. The lower ends of the levers 72 and are provided, as hereinbefore described, with jaws 7 6,which operate at the base of the teeth on one side of the saw,and the lower ends of the levers 73 and 74 are provided with setscrews 7 8, which operate in connection with the points of the teeth on the opposite side of the saw, and these set-screws, as will be understood, may be so set as to give the teeth of the saw an y desired inclination, and at each operation of the lever 59 or at each double movement thereof the levers 72 and 74 at one end of the shaft 60 operate on a tooth and set it in the proper direction, and at the next full movement of said lever 59 said levers 72 and 74 skip a tooth and operate on the alternate tooth, and as the saw is carried along the levers 7 3 and 75 at the opposite end of the shaft 60 operate on the teeth which are skipped by the levers 72 and 74 and set them in the op posite direction. This operation is accomplished by means, as hereinbefore described, of the cams 67, 68, 69, and 70, the cams 67 and 69 operating in connection with the levers 73 and 75 and the cams 68 and 70 operating in connection with the levers 72 and 74.

As the filing devices and the setting devices are operated in the manner described the saw is moved longitudinally thereof and longitudinally of the plates 36 and 41 by means of the jaws 43, between which it is held and by which it is carried, and by means of the feeding devices hereinbefore described, which consist of the lever d the rod d, and the parts connected with said lever. This operation is accomplished by means of the shaft 29, the tooth 61*, and the arm 9 of said lever, and as the shaft 29 revolves the lever d is operated, so as to move the rod d to the right, in which operation the pawls d engage with the teeth of the saw and carry it to the right each time that the shaft 29 revolves, this operation being accomplished by the tooth 61 which operates in connection with the arm g of the lever (1 and each time that the teeth 01 pass the arm g the spring 71 throws the rod 01 to the left and the pawls d engage with other teeth of the saw. I
